6120EG4 Heavy Drum Road Roller

6120EG4 20-Ton Heavy-Duty Single-Drum Vibratory Road Roller for Large-Scale Subgrade Compaction Large-scale highway upgrades, mining road renovations and industrial site hardening works often encounter a key construction dilemma. Most conventional compaction machines lack sufficient dead weight and vibration output, failing to compact deep subgrade layers thoroughly and consistently, which makes it hard to pass strict modern engineering acceptance standards. This common industry issue leaves many construction teams facing frequent pavement settlement rework, inefficient equipment matching and continuously rising long-term maintenance expenses. Developed to solve heavy-load and large-area compaction challenges, the 6120EG4 is a professional 20-ton single-drum vibratory road roller. Equipped with a high-torque power assembly and dual-frequency adjustable vibration system, it reliably completes subgrade filling compaction, stabilized base layer densification and overall site leveling wor…
